I have used bird grit for 27 years and finally I have found what I consider to be the absolute best Finch grit available. This grit is composed of the finest ground shell with natural trace minerals and sea salts. It is perfect for all small cage birds. (Finches, Parakeets, Doves and Quail) We keep this grit in every cage and every flight and offer it continuously to our birds. They devour it!
